KEY MESSAGES

- Quiet weather expected through the weekend.

- Outside of a system centered around Wednesday, mainly dry conditions are forecast to prevail until late next week.

SHORT TERM /THROUGH SUNDAY/

Issued at 145 PM CDT Sat Aug 22 2026

As low pressure organizes over the eastern Great Lakes region, a large area of high pressure will set up over the Mid to Upper Mississippi Valley. This will lead to beautiful late summer weather locally with highs in the upper 70s to lower 80s, comfortable humidity, and overnight lows in the 50s!

LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/

Issued at 145 PM CDT Sat Aug 22 2026

Northwesterly flow aloft is forecast to continue through much of the next week with some operational models showing a transition to more zonal flow across the CONUS to end the next week. Although there are numerous disturbances moving through the flow passing near the area, the next more widespread chance (20 to 30%) for showers and storms appears to be late Tuesday night through Wednesday when a stronger shortwave moves across the region. Any rainfall amounts will be light through the middle of next week.

Monday is expected to be the coolest day of the period with highs in the mid 70s to near 80 degrees. High temperatures the rest of the week are forecast to be in the lower to mid 80s. Tuesday night onward, low temperatures are forecast to be in the lower to mid 60s.

AVIATION /18Z TAFS THROUGH 18Z SUNDAY/

Issued at 1138 AM CDT Sat Aug 22 2026

VFR will prevail through the period with high pressure in control. Steady NW winds (10-20 kts) through the day will subside by this evening.
